Description
Раствор упаривают и полученные кристаллы отфильтровываютс . Содержание в них сурьмы в пересчетеThe solution is evaporated and the resulting crystals are filtered off. The content of antimony in terms of
на трехокись близко к 77%, что отвечает соли состава 4 SbFg. . Если при разложении трехокиси былthe trioxide is close to 77%, which corresponds to the salt of composition 4 SbFg. . If the decomposition of the trioxide was
применен значительный избыток плавиковой кислоты, то дл реакции может быть вз т раствор фтористого аммони , полученный путем нейтрализации плавиковой кислоты аммиаком по фенолфталеину.Since a significant excess of hydrofluoric acid is used, an ammonium fluoride solution obtained by neutralizing hydrofluoric acid with ammonia over phenolphthalein can be taken for the reaction.
Этот раствор приливаетс , согласно расчету, к раствору фтористой сурьмы , и так как содержащийс в нем средний фтористый аммоний неустойчив и легко гидролизуетс по уравнению:This solution is added, according to the calculation, to the antimony fluoride solution, and since the ammonium fluoride contained therein is unstable and easily hydrolyzed by the equation:
(NH,),F2 + НОН: NH.OH 4- NH.F.HF(NH,), F2 + HOH: NH.OH 4- NH.F.HF
с образованием свободного гидрата аммони , то это приводит к м гкой нейтрализации раствора фтористой сурьмы.with the formation of free ammonium hydrate, this leads to a mild neutralization of the solution of antimony fluoride.
Однако нужно отметить, что и с кислым фтористым аммонием процесс идет гладко, так как свободна плавикова кислота в значительной мере удал етс при упаривании.However, it should be noted that the process proceeds smoothly with acidic ammonium fluoride, since the free hydrofluoric acid is largely removed during evaporation.
Предмет изобретени .The subject matter of the invention.
Способ получени двойной соли фтористоаммонийной сурьмы 4 SbFj. смешением растворов SbFg и , отличающийс тем, что обработку раствора SbFj ведут в кислой среде, например, введением в процесс кислой фтористоаммонийной соли .HF, либо прибавлением твердой фтористоаммонийной соли NH4F в раствор фтористой сурьмы SbF, содержащий свободную плавиковую кислоту.The method of obtaining the double salt of fluoride ammonium antimony 4 SbFj. by mixing SbFg solutions and characterized in that the SbFj solution is treated in an acidic medium, for example, by introducing the acidic .HF acid fluoride salt into the process, or by adding solid NH4F fluoride ammonium salt to the SbF fluoride solution containing free hydrofluoric acid.
